DlSK OR ROTARY PLOW.

SPECIFICATION forming part of Letters Patent No. 742,908, dated November3, 1903. Application filed August 26, 190].- Serial No- 73.296. (Nomodel.)

To aZZ whom it ntaty concern.-

Be it known that I, NEWELL SANDERS, a citizen of the United States,residing at Ghattanooga, Tennessee, have invented certain new and usefulImprovements in Plow-Disks, of which the following is a specification.

My invention relates to improvements pertaining to disk or rotary plows;and the object of the invention is to produce an improved means forsupporting the scraper whereby it may be readily adjusted to regulatethe discharge of the dirt from the disk while maintaining the properrelation between the edge of the scraper and the concave face of thedisk.

I have illustrated the invention in the accompanying drawings, in which-Figure 1 is an elevation showing the plow disk and scraper. Fig. 2 is asectional view. Fig. 3 is a sectional detail showing thetongueand-grooved connection between the bracket and scraper-support,and Figs. 4 and 5 are detailviews of the scraper-adjusting block.

Fig. 6 is a cross-sectional view of the end of the scraper-standard,showing the curved seat.

In the drawings, A indicates the plowframe, which is supported by theusual land and furrow wheels. As these form no part of the presentinvention they are not described in detail. Bolted to the frame A is adisk box B, which carries the bearing 1) for the rotary plow-disk G, andas the manner of mounting the disk in its bearing forms no part of thepresent invention more specific description thereof is deemedunnecessary. Upon the upper side of the disk-box is a fanshapedextension D, to which the scraperstandard is designed to be secured insuch a manner as to permit of its radial adjustment with relation to theaxis of the plow-disk. I prefer to provide for this radial adjustment byforming the face of the fan-shaped extension D with a plurality of ribs(1, formed on lines radially from the axis of the plow-disk. Thescraper-standard E is provided with a groove to correspond with theseribs, and both the scraper-standard and the disk are provided withopenings for the passage of clamping-bolt, and the opening or openingsin these parts are preferably made elongated for the purpose of raisingor lowering of the scraper.

The scraper-standard consists, preferably, of a fiat bar of metal, whichis carried upward 0n the rear of the disk and downward at the front,where it terminated in a suitable connection for the scraper, thisconnection comprising a washer-plate F, having its front and rear facesf and f curved in opposite directions. The rear curved face seats in acorrespondingly-curved seat in the front lower end of the standard,while the front curved face is fitted to correspondingly-curved portionof the bracket G, which is secured to the scraper H, or vice versa. Abolt 1, passing through suitably-elongated openings in the bracket,standards, and washer, connects these parts firmly together. If desired,these parts may be serrated on their adjoining faces to hold them morefirmly against slipping. If desired, the fan-shaped extension might besecured directly to the frame.

From the above description it will be seen that I provide an extremelysimple and effective means for supporting the scraper, which enables meto adjust the scraper to any desired position and to maintain exactlythe proper relation between the scraper and the curved face of the diskto secure the best results.

I claim- 1. The combination with the plow-frame and rotary disk, of ascraper-standard of substantially inverted- U shape having its dependingarms located in front and rear of the disks, means for adjustablysupporting the rear arm from the frame whereby it may be adjustedradially of the disk, and a scraper carried by the front arm,substantially as de-. scribed.

2. The combination with a frame and plowdisk, of a fan-shaped extensionor bracket plow-disk, a scraper-standard having one end connected tosaid fan-shaped extension so as to be radially adjusted with relationthereto, said standard extending up over the edge of the plow-disk anddown in front thereof and a scraper adj ustably connected with the frontend of said standard, substantially as described.

supported by said plow-beam in rear of the ICO 3. The combination withthe frame of a disk box having a plow-disk journaled thereon, afan-shaped bracket or extension carried on p the upper side of said diskbox and a scraperstandard adjustable on said bracket on lines radiallyfrom the axis of the plow-disk anda scraper supported by said standard,substantially as described.

4. The combination with the frame and plow-disk, of a scraper-standardsupported by said frame and extending in front of the disk, aWasher-plate having its front and rear faces positively curved inopposite directions, the rear face engaging a correspondinglycurved seatin the standard, a bracket having a curved seat engaging the front faceof the Washer, a bolt passing through said parts for holding themtogether and a scraper carried by the bracket,substantially asdescribed.

5. The combination with the frame and NEWELL SANDERS.
